The fact that they arc eminently imsaturated compounds is
evidenced by their general behaviour towards a great variety
of reagents.

1.   On reduction they give the primary amine (Mendius),

2.   With HC1, ITIir, and HI they form imidohalides (Wallach),

3. With alcohol and II Cl they form the hydrochloride of the
imidoethers, from which caustic alkali liberates the base

These imidoethers unite with ammonia and amines and form
the amidines,


4. The latter are also formed by the direct action of ammonia
on the cyanide,

Methylamine Hydrochloride.- -This reaction, which
yields the primary amine, is applicable, not only to the aliphatic,
but also to the aromatic amides. The formation of anthranilic acid
from phthalimide is a process of technical importance. By the
